[0026] In order to make those skilled in the art better understand the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort should fall within the scope of the present application.

[0027] Embodiment one

[0028] Figure 1 The flowchart of the parking lot space management method provided by an embodiment of the present application can be applied to the scenario of managing spaces in a large parking lot. The method can be executed by a parking lot space management device, which can be realized in the form of hardware and / or software, and can be configured in an electronic device.

[0029] As shown in Figure 1 , the parking lot space management method comprises:

[0030] S101, real-time receiving of space state information of each space in the parking lot; wherein the space state information is obtained by identifying real-time collected space pictures through a space camera installed above the space; and each space camera is externally provided with a Bluetooth transmitter.

[0031] The parking lot related to the embodiment of the application can be a large parking lot matched with a place such as a shopping mall, a shopping center or a large complex; the parking lot can be single-layer or multi-layer. A plurality of parking spaces are arranged in the parking lot, each parking space is marked by a boundary line or a boundary point, and different marks are marked in each parking space; meanwhile, a plurality of parking space cameras are installed in the parking lot, the visual angle of each parking space camera can cover a plurality of parking spaces, and there are overlapping parking spaces at the visual line edge of adjacent parking space cameras. A low-illumination CMOS recognition algorithm based on vehicle contour and license plate features is pre-deployed in each parking space camera, the algorithm is a computer vision technology specially designed to accurately identify vehicles and license plate information in insufficient light environment, the algorithm combines vehicle contour feature extraction and license plate recognition technology, and is optimized for the imaging characteristics of the CMOS sensor under low-illumination conditions. In addition, a Bluetooth transmitting device is externally arranged on each parking space camera, and the Bluetooth transmitting device can be a BLE signal broadcasting device (such as iBeacon).

[0032] On this basis, each parking space camera shoots real-time pictures of the parking space at a fixed frequency (such as 1 time per second) to cover the panorama of the parking space (including the ground marking line and the vehicle that can be parked). Further, the parking space camera analyzes the collected pictures based on the built-in low-illumination CMOS recognition algorithm based on vehicle contour and license plate features: if a vehicle contour (or license plate) is detected in the picture, it is determined that the parking space is occupied; if no vehicle is detected, it is determined to be idle; wherein the occupied or idle parking space belongs to the parking space state information, and the license plate number and parking time of the vehicle occupying the parking space also belong to the parking space state information. The parking space camera uploads the recognized parking space state information (including the parking space number, state, and time stamp) to the parking lot management system in real time through wired (such as Ethernet) or wireless (such as Wi-Fi) mode, so that the server in the parking management system processes it.

[0033] S102, according to the binding relationship between the turnout and the parking space in the parking lot, and in combination with the parking space state information of each parking space in the parking lot, the remaining parking space guide information displayed on the guide screen at the turnout in the parking lot is controlled.

[0034] In the embodiment of the application, the binding relationship between the turnout and the parking space can be a pre-set topological association (such as “turn left at No. 1 turnout corresponds to A area parking space, and turn right corresponds to B area parking space”), which is used to clearly define the target area of the turnout guide. The guide screen is an electronic display screen installed at the turnout, which is used to display the number of remaining parking spaces and the direction to the car owner. The remaining parking space guide information is the idle parking space data of the area calculated based on the parking space state (such as “A area has 5 remaining parking spaces, please turn left”), which assists the car owner to quickly find an empty space.

[0035] In specific implementation, the server in the parking space management system first calls the binding relationship between the fork roads and parking spaces in the parking lot. For example, the main fork road on the first floor includes three driving directions: left turn, right turn, and straight ahead, and the three driving directions are respectively bound to three parking space areas A, B, and C. Then, the remaining parking spaces are calculated, mainly by combining the real-time parking space status received in step S101, and statistically counting the number of remaining idle parking spaces by area (for example, there are 20 parking spaces in area A, 15 of which are currently occupied, and 5 are remaining). Further, guidance information is generated. Specifically, for each fork road, appropriate guidance content is generated, including direction indication and remaining quantity (such as "Turn left to area A: 5 parking spaces remaining", "Turn right to area B: 2 parking spaces remaining"). Further, the system sends a control instruction to the fork road guidance screen through a communication protocol (such as RS485) to drive the screen to display the generated guidance information, ensuring that the vehicle owner can quickly select a direction at the fork intersection.

[0036] S103. After the target vehicle stops at the target parking space according to the remaining parking space guidance information, receive the binding relationship data of the target parking space and the target vehicle uploaded by the parking space camera.

[0037] In an embodiment of the present invention, when the target vehicle drives into and stops stably at the target parking space, the parking space camera confirms that the vehicle completely occupies the parking space through image recognition (such as detecting the vehicle in 3 consecutive frames of images). The binding relationship is generated mainly by associating the unique identifier of the parking space (such as "A10 on the 3rd floor") with vehicle characteristics (such as license plate, vehicle type, preferably license plate) to generate binding relationship data (format example: {"vehicle_id": "Beijing AXXXXX", "parking_space": "3 - A10", "floor": 3}). Then, the parking space camera stores the binding relationship data in the system database and synchronizes it to the background of the vehicle search APP that the vehicle owner may use (associating the vehicle owner's account through the license plate, or allowing the vehicle owner to scan the code for binding).

[0038] S104. When the vehicle owner triggers reverse search for the target vehicle through the mobile terminal, determine the real-time position of the mobile terminal according to the Bluetooth signal received and uploaded by the mobile terminal from the Bluetooth transmitter in real time; generate and display a real-time vehicle search navigation path according to the real-time position of the mobile terminal and the position of the target parking space in the binding relationship data to guide the vehicle owner to search for the vehicle.

[0039] In the embodiments of the present application, reverse car searching refers to the behavior of a car owner searching for a parked vehicle from any position in a parking lot. The mobile terminal refers to the car owner's mobile phone or other device supporting Bluetooth signal reception and APP operation. The Bluetooth signal refers to the BLE signal (including device ID, signal strength RSSI, etc.) broadcast by the Bluetooth transmitter device of the parking space camera, which is used to locate the mobile terminal in real time. Real-time location determination refers to calculating the current location of the car owner through the Bluetooth signal received by the mobile terminal. Real-time car searching navigation path refers to the dynamically planned route from the current location of the car owner to the target parking space.

[0040] On the basis of the above, the car owner uses the mobile terminal (mobile phone) to open the car searching APP by scanning the car searching two-dimensional code, clicks the "find car" control, and the system receives the reverse car searching request and calls the binding relationship data corresponding to the car owner (determines the target parking space position: such as 3A10). Further, the mobile terminal locates in real time, mainly the Bluetooth of the mobile phone is turned on, scans the signals broadcast by the Bluetooth transmitter device of the surrounding parking space camera, and obtains the IDs and RSSIs (signal strengths) of multiple Bluetooth transmitter devices; the mobile phone uploads the signal data to the system, and the system determines the current real-time location of the car owner (such as "1st floor elevator entrance") through the fingerprint positioning method (comparing the real-time RSSI with the pre-stored "position-signal fingerprint" database) or the triangulation method (distance calculation based on multiple signal sources).

[0041] In some embodiments, according to the real-time location of the mobile terminal and the position of the target parking space in the binding relationship data, a real-time car searching navigation path is generated and displayed to guide the car owner to search for the car, including steps A-F:

[0042] A. According to the real-time location of the mobile terminal, determine the current floor of the mobile terminal in the parking lot.

[0043] Among them, the real-time location of the mobile terminal is the current spatial coordinates of the car owner calculated by the Bluetooth signal received by the mobile terminal in real time. The current floor is the parking lot floor (such as 1st floor, 3rd floor) where the car owner is based on real-time location information, which is the basis for cross-floor navigation.

[0044] In a specific implementation, the system receives real-time position coordinates uploaded by the mobile terminal, which contains implicit floor information (or separate Z-axis data, such as Z=1 representing the first floor). Through a preset "coordinate-floor" mapping relationship (such as "Z=1→1 floor, Z=3→3 floor"), the current floor of the vehicle owner (such as "1 floor") is directly analyzed. If there is no explicit floor information in the coordinates, the system combines the ID characteristics of the current floor Bluetooth transmitting device (such as all 1 floor device ID prefix "F1-"), and further confirms the current floor through the signal source to avoid floor misjudgment caused by positioning errors.

[0045] B. According to the position of the target parking space, determine the target floor of the target parking space in the parking lot.

[0046] Among them, the target parking space position refers to the specific space coordinates (including floor, X, Y axis position corresponding to parking space number) of the target vehicle parking, stored in the binding relationship data. The target floor is the floor information (such as "3 floor") extracted from the target parking space position information, which is used to judge whether cross-floor navigation is needed.

[0047] In a specific implementation, the system extracts the position information of the target parking space (such as "3A10, coordinates X=120, Y=80, Z=3") from the "target vehicle-target parking space" binding relationship data. In this way, the floor parameter (such as Z=3→target floor "3 floor") can be directly read from the position information, or the parking space number rule can be analyzed (such as "3" in "3A10" represents the third floor).

[0048] C. In response to the current floor and the target floor not being the same floor, determine the target elevator port closest to the real-time position in the current floor map of the parking lot.

[0049] In the embodiment of the application, the system compares the current floor (such as 1 floor) and the target floor (such as 3 floor), and if it is confirmed that the floors are different, the cross-floor navigation logic is triggered. Specifically, from the topological database of the current floor map, the position coordinates of all elevator ports (such as 1 floor elevator port coordinates X=70, Y=50) are retrieved. Taking the real-time position of the vehicle owner (such as X=50, Y=30) as the starting point, the straight-line distance or the actual travel distance (considering the channel direction) to each elevator port is calculated, and the elevator port with the shortest distance is selected as the "target elevator port" (such as 1 floor elevator port A, distance 20 meters).

[0050] D. According to the real-time position of the mobile terminal and the position of the target elevator port, a first real-time car searching navigation path is planned in the current floor map of the parking lot to guide the vehicle owner to move to the target elevator port to take the elevator.

[0051] Optionally, the system loads a topology map of the current floor (e.g., floor 1), including information such as passable passages, obstacles (pillars, walls), and nodes (passage intersections). Then, using the driver's real-time location (i.e., the mobile terminal's real-time location) as the starting point and the target elevator entrance as the destination, a preset path planning algorithm is used to plan the shortest path (prioritizing routes with shorter distances and fewer turns). For example, the path might be: "Current location → go straight for 10 meters to the passage intersection → turn right and go straight for 10 meters → arrive at elevator entrance A on floor 1". In the mobile car-finding app, the path is displayed with highlighted lines and arrow icons, and key nodes are marked (e.g., "Turn right in 5 meters ahead"), while triggering voice prompts (e.g., "Please go straight to the elevator entrance").

[0052] E. In response to the cross-floor navigation operation triggered after the car owner takes the elevator to the target floor of the parking lot, the real-time location of the mobile terminal is determined based on the Bluetooth signal received and uploaded in real time from the Bluetooth transmitter of the parking space camera on the target floor.

[0053] In this embodiment of the invention, the arrival of the vehicle owner at the target floor (e.g., the 3rd floor) can be detected in the following two ways:

[0054] Elevator beacon trigger: When the elevator arrives at the 3rd floor, the internal beacon broadcasts a "3rd floor arrived" signal, which is received by the mobile terminal and automatically notifies the system.

[0055] User confirmation: After exiting the elevator, the car owner clicks "Arrived at the 3rd floor" in the car-finding app to trigger cross-floor navigation.

[0056] Upon reaching the target floor, the mobile terminal scans the Bluetooth transmitter signals of the parking space cameras on the target floor (3rd floor) to obtain the IDs (such as "3A09", "3A10") and RSSI (signal strength) of multiple devices. The system then uses a fingerprint positioning method (comparing the real-time RSSI with the "location-signal fingerprint" database pre-stored on the 3rd floor) to determine the car owner's real-time location on the 3rd floor (such as "3rd floor elevator entrance B, coordinates X=90, Y=60").

[0057] F. Based on the real-time location of the mobile terminal and the location of the target vehicle, plan a second real-time vehicle navigation route on the map of the target floor to guide the car owner to the target parking space.

[0058] In the embodiment of the present application, the system switches to the topological map of the target floor (3rd floor), which contains information such as the passageway of the floor, the distribution of parking spaces (for example, the coordinates of the 10th parking space in area A of the 3rd floor are X=120 and Y=80), and the like. The navigation path is planned with the real-time position of the target floor (for example, the elevator port B of the 3rd floor) as the starting point and the target parking space (the 10th parking space in area A of the 3rd floor) as the end point. At the same time, the mobile terminal updates the real-time position of the vehicle owner (by continuously scanning the 3rd floor Bluetooth signal), and if the position deviates from the path (for example, more than 2 meters), the system automatically re-plans the path and guides the vehicle owner to the target parking space through voice (for example, “a new route has been planned for you. Please turn left”) and visual cues.

[0059] In the embodiment of the present application, if the target parking space and the current real-time position of the mobile terminal are on the same floor, the real-time navigation path of the same floor can be directly planned according to the updated position of the vehicle owner of the mobile terminal and the position of the target parking space to guide the vehicle owner to move to the target parking space.

[0060] In addition to the dynamic vehicle searching described above, a fixed navigation route can also be generated to guide the vehicle owner to search for the vehicle. Specifically, in response to the vehicle owner scanning the vehicle searching two-dimensional code by using the mobile terminal, a vehicle searching interface is displayed, and the vehicle owner is prompted to input the license plate number of the target vehicle. According to the pre-stored binding relationship between the vehicle and the parking space, the vehicle picture corresponding to the license plate number of the target vehicle, the target parking space information, and the entry time information are determined and displayed on the mobile terminal. In response to the vehicle owner triggering the vehicle searching route function on the mobile terminal, a fixed vehicle searching path is planned according to the position of the target parking space and the current position of the mobile terminal and is displayed on the mobile terminal, so that the vehicle owner can search for the vehicle according to the fixed vehicle searching path displayed on the mobile terminal.

[0061] In the embodiment of the present application, the guide screen at the fork in the parking lot displays the number of remaining parking spaces generated by different forks leading to different directions, effectively guiding the vehicle owner to park smoothly, and solving the problem of difficulty in parking in the parking lot. When searching for the vehicle, the vehicle searching navigation path is dynamically planned based on the received Bluetooth signal, improving the efficiency of searching for the vehicle and solving the problem of difficulty in searching for the vehicle in the parking lot.

[0062] Embodiment two

[0063] Figure 2 A flowchart of a parking lot parking space management method provided in the embodiment of the present application. In the embodiment, in addition to searching for the vehicle by using the mobile terminal, the vehicle can also be searched by using the inquiry machine. Specifically, refer to Figure 2 The parking lot parking space management method comprises the following steps:

[0064] S201, real-time receiving of parking space state information of each parking space in the parking lot; wherein the parking space state information is obtained by recognizing the real-time collected parking space pictures by the parking space camera installed above the parking space; each parking space camera is externally provided with a Bluetooth emitting device.

[0065] S202, according to the binding relationship between the turnout and the parking space in the parking lot, combining the parking space state information of each parking space in the parking lot, the guide screen at the turnout in the parking lot is controlled to display the remaining parking space guide information.

[0066] S203, in response to the target vehicle parking at the target parking space according to the remaining parking space guide information, the binding relationship data between the target parking space and the target vehicle uploaded by the parking space camera is received.

[0067] S204, in response to the car owner inputting any one of the license plate number of the target vehicle, the parking time, and the number of the target parking space in the query machine, the vehicle attribute information and the vehicle parking information corresponding to the target vehicle are displayed in the query machine in the form of pictures, and the navigation route between the position of the target parking space and the position of the query machine is displayed in the query machine, so that the car owner can find the target vehicle according to the navigation route.

[0068] In some embodiments, in response to the car owner triggering the license plate query function in the query machine and inputting the license plate number, the vehicle attribute information (including vehicle pictures, license plate numbers, etc.) corresponding to the license plate number and the vehicle parking information (including parking time, parking time, etc.) are displayed in the query machine in the form of pictures; the navigation route between the position of the target parking space and the position of the query machine is displayed in the query machine, so that the car owner can find the target vehicle according to the navigation route.

[0069] In some embodiments, in response to the car owner triggering the time query function in the query machine and inputting the parking time, the vehicle attribute information and the vehicle parking information corresponding to the parking time are displayed in the query machine in the form of pictures; in response to the car owner selecting the target vehicle from the displayed pictures, the navigation route between the position of the target parking space and the position of the query machine is displayed in the query machine, so that the car owner can find the target vehicle according to the navigation route.

[0070] In some embodiments, in response to the car owner triggering the parking space query function in the query machine and inputting the parking space number, the vehicle attribute information and the vehicle parking information corresponding to the parking space number are displayed in the query machine in the form of pictures; after the car owner determines the target vehicle, the navigation route between the position of the target parking space and the position of the query machine is displayed in the query machine, so that the car owner can find the target vehicle according to the navigation route.

[0071] Further, in response to the car owner's picture zoom request, the pictures displayed in the query machine including the vehicle attribute information and the vehicle parking information are zoomed to avoid the car owner being unable to clearly see the vehicle attribute information and the vehicle parking information because the pictures are too small.

[0072] In the embodiment of the present application, the parking space camera is further used for: identifying according to the real-time collected parking space pictures, if a vehicle is parked with line pressure, an alarm is given, and if a vehicle parked on the parking space has no license plate, the data of the binding relationship between the vehicle without license plate and the parking space is reported. Since the parking space camera can also report the data of the binding relationship between the vehicle without license plate and the parking space, when searching for a vehicle, the vehicle owner can trigger the vehicle searching function of the vehicle without license plate to achieve the purpose of searching for the vehicle. For details, refer to step S205.

[0073] S205, in response to the vehicle owner triggering the vehicle searching function of the vehicle without license plate in the query machine, the information of all vehicles without license plate is displayed in the query machine; in response to the vehicle owner selecting a certain vehicle without license plate, the parking space where the vehicle without license plate is located is determined according to the binding relationship data between the vehicle without license plate and the parking space; the navigation route between the location of the parking space and the location of the query machine is displayed in the query machine, so that the vehicle owner can search for the vehicle without license plate according to the navigation route.

[0074] In the embodiment of the present application, in addition to the above-mentioned steps for searching for a vehicle, the use of parking spaces in the parking lot can also be counted, for details, refer to step S206.

[0075] S206, according to the real-time received parking space state information of each parking space in the parking lot, the guide screen at the entrance of the parking lot is controlled to display the remaining parking space information of each floor of the parking lot; or, according to the real-time received parking space state information of each parking space in the parking lot, the traffic flow of the parking lot is counted.

[0076] In the embodiment of the present application, the system continuously receives the state data (occupied / idle) of each parking space in the parking lot through the network (such as a local area network, a wireless network). These data come from the parking space camera above the parking space. The parking space camera takes pictures of the parking space in real time, judges the parking space state through image recognition technology, and uploads the result (such as "occupied" and "idle") to the system server in real time. The system classifies and counts all the received parking space state information according to the floor, traverses the position information (pre-stored in the system database, including the floor to which it belongs) of each parking space, respectively calculates the number of parking spaces in the idle state of each floor, and obtains the remaining parking space data of each floor. The system sends the remaining parking space data of each floor to the guide screen control module at the entrance of the parking lot, and the control module drives the guide screen to display in the form of text, icon or number in real time, for the reference of the vehicle owner entering the parking lot, to assist him in selecting the floor. In addition, the system takes the parking space state at the initial time (such as a certain hour) as the reference, or sets a fixed time window (such as every 5 minutes), counts the number of parking spaces that change from "idle" to "occupied" in the unit time, that is, the number of newly parked vehicles. Count the number of parking spaces that change from "occupied" to "idle" in the unit time, that is, the number of vehicles that have left. The system can update the above data in real time, generate cumulative flow or instantaneous flow (such as "200 vehicles have entered in the current 1 hour, and 150 vehicles have left"), and can be used for subsequent flow monitoring, congestion warning and other functions.

[0077] The embodiment of the present application effectively solves the problem of difficult parking and searching in a parking lot.
